[Worms and the lung].

Due to international travel and migration helminthic infections are increasingly imported to countries were they are not endemic. A vast variety of helminthes may involve the lung. The lungs are either site of the infection or temporarily involved during maturation of helminthic larvae. In many affected patients the clinical picture is not specific and not typical. A thorough patient's history including a detailed travel history will lead to diagnosis, which must be confirmed by detecting the parasite either directly or with serological tests. The appropriate method depends on the parasite suspected and its life cycle within the human body. A combination of these methods will show the best results for most helminthes. As specific therapy is widely available for most helminthiases a precise diagnosis is important.
